Forcing onPress to react on the exact shape, rather then on the bounding box
If I have a clip with an imported image then clip.onPress
reacts on the
bounding box of the clip rather then on the exact shape of
the imported
image even if the imported image has a transparent
background.
To make it to react to in image shape only I have to use
Trace BitMap which
results in deterioration of the image quality and if the clip
is moving,
Trace BitMap also slows down computer perfprmance.
Is there other technique to make onPress to react on the
exact shape, rather
then on the bounding box?
An image is always rectangular, it just may have transparent
parts. So an MC containing an image is always as big as the whole
image (at least).
You could use the MovieClip.hitArea property, and create
another MC inside your clip that specifies the active area for
mouse clicks. This is easy if you have the image loaded into the
clip inside the Flash IDE.
If it's loaded on runtime, you might use the BitmapData class
(if you use Flash 8) to get the pixel value of the image at the
position where the image was clicked, check if it's transparent or
opaque, and decide whether to call the onPress action or not.

Why can't I see the bounding box for objects on the pasteboard?
Adobe CC sucks. Why last week was I able to see the bounding box of objects that I had on the pasteboard in InDesign CC, including objects that didn't contain anything yet, and now suddenly this week I can't see them?
It seems as though every week something inexplicably gets changed around. First Save As had no shortcut, then suddenly the shortcut is back, but it doesn't work.
Get it together Adobe. I don't want to be paying a subscription for a product that feels as though it's still in Beta mode.Hi Steve,
Yes thanks, I don't think I was clear in what I wrote. I knew that they could be turned back on, but why did I open InDesign this morning to find my workspace/preferences different than how I left them on Friday?
And I know it isn't a case of my mistakenly turning off the frame edges, because the operator that sits next to me had the exact same thing happen to her copy of InDesign this morning also.
I understand the requirement to update things, but it really does feel as though I'm using software that is still in testing. -

Why are my Illustrator images getting thicker strokes when I take the bounding box and make them smaller? This has never happened to me. I'm not an expert at Illustrator, but I do know some fundamentals.
Thank you for responding so quickly. No apologies necessary - I know this Forum isn't McDonalds - don't expect an answer to be served up right away. You helped me out with a big issue yesterday.
I am using a mac - OSX 10.7.5
I have Adobe Creative Suites - CS5 - Illustrator version is 15.0.2
The contents I am placing are all Vector - Illustrator files
But, I wonder about some of the vector files I work with. Could a "line weight/thickness" be 'assigned' to the drawing and screw things up? I used 'simple' linear (line) drawings from SolidWorks that have been converted to ai files. It's just weird because I checked the stroke of the drawing and it's not out of line.
I am attaching part of some box labels. You can see how the drawings, of the products, on the 'left side' are "thick" after embedding them. I think the "Global Logo" was pasted into a template not linked that's why it's okay. But look at the Quiet Thunder logo - it looks terrible. These labels are only 2.25" X 6.5", so its important I keep the images lightweight.
Your help is very much appreciated. Thank you! -
Can PB can calcute the bounding box as the needed region in AE?
Hi,
I wrote many small pixel bender that I use mainly in AE. However I need them to be as efficient as possible, so I wonder if Pixel Bender can obtain the bounding box of an image input as the needed region. This way, it will not calculate an entire frame when there is only a few pixels in the frame.
Thanks
Jocelyn TremblayHi,
I did a major breakthrough by rethinking the model. Now I get a real speed improvment, and if the image is fully opaque, there is not too much drawback.
Instead of a simple bounding box, I'm creating a grid in which each cell represent a region of the source and is float4(1). if there is any non-zero transparent pixel. In the last kernel of the graph, i'm processing only when the corresponding value in the grid is float4(1.). I get really efficient results from that. I'm including two graphs. A basic one with a fixed grid of 16px (I didn't do any beanchmark for the grid size) where I output the original image composited over the scaled grid in green. The second one, where the last kernel is a box blur, the grid size equal the blur radius, and there is a convolution kernel between the grid and the box blur that expand the grid to fit the blur.

Changing the bounding box size
When I go to print an image in Photoshop CC, a dialogue box appears and on the left-hand side is the image to be printed. Bordering the image are small diagonal lines which I'm assuming are the bounding box. The distance between the edge of the page varies from side to side and I want to center the photo. I can't see how to do that.
Thanks.The print dialog preview area show basically three areas. The Paper size the printer is set to and the sizes are displayed with numeric unites. If you see small diagonal lines these are showing the areas the printer can not print on with the current settings. With different printer setting this area may change for example if the printer support borderless the side non printable may go way but there still be some top and bottom non printable area. The Bottom non printable area may go away if you switch from sheet feed to roll paper feed. Inside the diagonal line is the printable area and inside that a bounding box of the image. If You check scale for media the image will be scaled to fit within the print area.

I have made some objects in 8-bit design style using rectangular grid tool.
I was working on the file, and i saved the file, and then illustrator crashed, and all the data in the 8 bit grid wasn't showing up, only the bounding boxes(rectangular-grid) of those 8-bit designed objects were present with no color/no fill.
I am attaching some screenshots and jpegs to show how it was before and how it is now.
Can somebody help me out in this?Illustrator crashed when saving and most probably took some of your file with it.

Lost the bounding box (scale handles)
HELP. I have lost the bounding box (scale handles) for only the Rectangle and Rounded Rectangle Tools. I have tried switching the view options on and off with no changes or improvements. How do I reset the presets or preferences. Will this help? Thanks
Robert,
There are a few more options.
As Larry said, the Live Rectangle bug is limited to the MAC versions starting with 10.7 and 10.8, but not 10.9 (Mavericks) or 10.10 (Yosemite). Hopefully, the bug will be fixed soon.
So a switch to Mavericks or Yosemite with a reinstallation might be the way to solve it here and now.
To get round it in each case, it is also possible to Expand the Live Rectangles to get normal old fashioned rectangles, or to Pathfinder>Unite, or to use the Scale Tool or the Free Transform Tool.
A more permanent way round that is to create normal old fashioned rectangles, after running the free script created by Pawel, see this thread with download link:

Resizing in Illustrator CC using the Bounding Box is no longer accurate. What happened?
In Illustrator CC, resizing an object using the bounding box is no longer accurate. Snapping to other objects or the grid or anything is completely wrong and, worse, inconsistent. Here is a single box being resized 3 times to the same object. Each time, it becomes a different size.
I used the center-left handle to resize the black box, snapping it to the right edge of the red box. You can see that, each time, it "snaps" to the edge incorrectly. My 80 pt box becomes 78.479 pt, then 79.295 pt, then 79.518 pt.
This is totally unacceptable, obviously. I'm not sure what the point of guides are if they aren't actually guiding. Does anyone have a fix for this?Ethan,
Did you reinstall after updating to Yosemite? I believe the right order/way is to update the OS first, then reinstall the applications, see 6) below.
Or you may have a look at the list since something is obviously wrong.
The following is a general list of things you may try when the issue is not in a specific file (you may have tried/done some of them already); 1) and 2) are the easy ones for temporary strangenesses, and 3) and 4) are specifically aimed at possibly corrupt preferences); 5) is a list in itself, and 6) is the last resort.
1) Close down Illy and open again;
2) Restart the computer (you may do that up to 3 times);
3) Close down Illy and press Ctrl+Alt+Shift/Cmd+Option+Shift during startup (easy but irreversible);
4) Move the folder (follow the link with that name) with Illy closed (more tedious but also more thorough and reversible);
5) Look through and try out the relevant among the Other options (follow the link with that name, Item 7) is a list of usual suspects among other applications that may disturb and confuse Illy, Item 15) applies to CC, CS6, and maybe CS5);
Even more seriously, you may:
6) Uninstall, run the Cleaner Tool (if you have CS3/CS4/CS5/CS6/CC), and reinstall.

Save only the bounding box region of image as png?
Hi,
I'd like to save each layer's item as png.
If possible, i'd like save only the bounding box of image(of an item), and the corresponding bounding box's origin/size info(relative to artboard's origin) somewhere as text file.
To do this,
I need to be able to get a bounding box of an item.
and possibly artboard's origin. (because I'm not sure where a bounding box's coordinate's origin is).
Thank you in advanceIf I understand you correctly you have one table with a bunch of yes/no values (SA, SC, SS, etc.). Then for each record in that table you want to output a string listing all the fields from the first table which = yes (i.e are checked). Perhaps
the following code would get you started:
Sub JimNeal()
Dim strProcedure_Value As String
Dim rst As DAO.Recordset
Dim rstOut As DAO.Recordset
Set rst = DBEngine(0)(0).OpenRecordset("TableWithCheckboxes")
Set rstOut = DBEngine(0)(0).OpenRecordset("OutputTable")
Do Until rst.EOF
strProcedure_Value = ""
If rst!SA Then strProcedure_Value = strProcedure_Value & "Surface Area,"
If rst!SC Then strProcedure_Value = strProcedure_Value & "Surface Contour,"
'... etc
If rst!SS Then strProcedure_Value = strProcedure_Value & "Steep Slope,"
rst.MoveNext
' Strip off final comma
If Len(strProcedure_Value) > 0 Then strProcedure_Value = Left(strProcedure_Value, Len(strProcedure_Value) - 1)
' Output the string to your output table
rstOut.AddNew
rstOut!Procedure_Value = strProcedure_Value
rstOut.Update
Loop
rst.Close
rstOut.Close
Set rst = Nothing
Set rstOut = Nothing

Where the bounding box and handles gone?
Today I had updated Illustrator 2014 to .1 and I did realized that bounding box are gone...
It works fine where two or more objects are selected but for one object it just disappeared...
How to get it back?Hi, thank you for your answer
It applies to plain rectangle tool, it looks like they just made changes to it and for now it doesn't behave as it was in version 18.0
When I do select two plain rectangle using a shift key then, bounding box is back again, ready to sue..
